[jdk11u-dev] RFR: 8277447: Hotspot C1 compiler crashes on Kotlin suspend fun with loop [v2]

[Goetz Lindenmaier]

> I backport this for parity with 11.0.15-oracle.
> 
> I had to do adaptions in the test:
>  * I changed the class file version from 62 to 55 in the .jasm file.
>  * I replaced  -XX:CompilationMode=quick-only by -XX:TieredStopAtLevel=3
>    because the flag CompilationMode is not in 11. I tried to reproduce the bug
>    with the new settings, but I can not see the bug. But I also can not reproduce
>    it with the original test and the original 17 release.  The test is passing with and 
>    without the fix.
